(b) Generate a permutation schedule using Campbell's procedure. Webnon-preemptive flow-shop problem is also shown to be NP-complete. The best known algorithms for all known NP-complete problems have a worst case computing time larger than any polynomial in the problem size. Fur- thermore, any NP-complete problem has a polynomial time algorithm iff all the others also have polynomial time algorithms [9—11].
